Abstract: The Radioanalytical Chemistry Section, as a part of the Central Division of Chemical Analysis of the Research Center KFA Jülich, has the task to provide and to applynuclear methods in the analytical service for the institutes and projects of the KFA and to customers outside. A great part of this service is trace element determinations by neutron activation analysis using the research reactor FRJ-2. The procedure for the instrumental technique is described and mainly practical aspects are reported in detail. It is based on the k$_{0}$-method developed by Simonits and DeCorte. The results are calculated from the peak areas of the $\gamma$y-lines and the corresponding k$_{0}$-factors. A new variant of this procedure is required, if the program used for the deconvolution of the $\gamma$-spectra provides absolute decay rates of the radionuclides instead of the $\gamma$-emission rates. This variant is also described. Some examples of analyses carried out in the analytical service are presented and discussed mainly with respect to accuracy of the results and detection limits.
